The Abbey of San Mercuriale (Italian: Abbazia di San Mercuriale) is the main religious building located in the Italian city of Forlì. It is located on the central square, near the Palazzo Comunale.
The tower of the Abbey of San Mercuriale, with its height of 75 meters, is one of the tallest in Italy. The first church on the site was destroyed by fire in 1173. The present structure was built with brick in the Lombard-Romanesque style and took only 7 years.
The colonnade to the right of the church is part of the abbey's cloister.
